I gave up trying to fix the existing systems and downgraded to stable.
Today, I took a test machine and reinstalled the entire system. There
were no improvements.
Winbind would panic at a "getent group" command every time. getent
passwd, wbinfo -u,
and wbinfo -g do not appear to cause this anomaly.
Output of the panic:
